J y the greatest opportunity, and 
the work that most needs doing in aaa era i is jantel 
giate ferns. Our large fern flora provides extensive material 
for this kind of work. If there is any truth in the concept of 
recapitulation, such studies should throw a flood of light on 
the relationships, and possibly on the phylogeny of the various 
groups. : 
_ Gymnosperms in general have received much attention. 
Little, however, seems to have been done with Indian forms. 
Serut of Lahore is working on Pinus longifolia, where the situa- 
tion appears to be the usual one for Pinus, and Saxton of 
Ahmedabad is undertaking Cedrus deodara. lt is likely that 
the study of life-histories of Indian gymnosperms will a 
little that is new to our knowledge, except possibly in the Gne- 
tales. Gnetum gnemon and G. scandens have been investigated, 
but it appears that there still are species @netum in Burmaand 
the Malay Peninsula, and of Ephedra in the Himalayas that 
have received no attention. Because of the unique character 
of the Gnetales, these unknown forms should be looked into. 
Collections for morphological purposes should be made when- 
ever opportunity offers. 
ie vascular anatomy of all Indian gymnosperms should 
prove interesting. Groom anp RusuTon* have investigated
